Environments
Localities
At the Kintore opencut, Broken Hill South Mine, Broken Hill, Broken Hill district, Yancowinna county, New South Wales, Australia, gartrellite
occurs on fine-grained quartz-spessartine rocks associated with
hidalgoite, beudantite,
segnitite, philipsbornite,
quartz and spessartine
(HOM, AJM 3.1.58, AM 75.932).
The gartrellite appears to preserve rough outlines of crystals of a hexagonal mineral, probably
mimetite, which have been dissolved
(AJM 3.1.58).
At the type locality, Ashburton Downs Station, Ashburton Shire, Western Australia, gartrellite occurs in an oxidised mineralised shear zone. It
is found as segregations in the compact masses of secondary minerals around
tennantite remnants, and also in veinlets penetrating tennantite,
sometimes associated with olivenite. Other associated minerals include
quartz, clay minerals,
iron oxides, and numerous secondary
copper minerals
(AM 75.932, HOM, AJM 13.1.37).
At the Tsumeb mine, Tsumeb, Oshikoto Region, Namibia, gartrellite is associated with mimetite,
duftite, beudantite,
bayldonite and quartz
(HOM)
